A hook cover 50 is attached to the hook 40. As shown in FIGS. 3 to 6, the hook cover 50 is formed in a cylindrical shape by an elastic body of urethane or the like having an energy absorbing function (for example, PE light (registered trademark) manufactured by Inoac Corporation). , Urethane is the most preferable mode.

The hardness T of the urethane hook cover 50 is, for example, 0.01 kN <T <0.5 kN. Further, although it depends on the shape and outer diameter of the hook 40, as an example, the axial length L (see FIG. 4) of the hook cover 50 is L = 75 mm to 100 mm, and the outer diameter Ro (see FIG. 6). ) Is Ro = 20 mm to 25 mm, and the inner diameter Ri (see FIG. 6) is Ri = 8 mm to 10 mm.

As shown in FIG. 2, the hook cover 50 is fitted and fixed so as to be entirely arranged in the locking region E with respect to the frame 62 in the hook 40. The locking region E is a region from the boundary portion (starting portion of the curvature of the first curved portion 44) 43 between the base portion 42 and the first curved portion 44 to the tip portion 48 side (up to the end surface 48A of the tip portion 48). The hook cover 50 is fitted at a position including at least a part of the first curved portion 44 on the straight portion 45 side, the straight portion 45, and the second curved portion 46.

In the following, the axial end of the hook cover 50 on the base 42 side is referred to as the "one end 51", and the axial other end of the hook cover 50 on the tip 48 side is referred to as the "other end 52". Further, as shown in FIG. 8, the end surface 52A on the compression deformation side of the other end 52 of the hook cover 50, which will be described later, is a boundary portion between the second curved portion 46 and the tip portion 48 (curvature of the second curved portion 46). It is designed to be located at 47).

As shown in FIGS. 4 to 6, the inner peripheral surfaces of the hook cover 50 at one end 51 and the other end 52 are each provided with double-sided tape 58 as an adhesive means, and the outer peripheral surface of the hook 40 at the first curved portion 44. The structure is such that the second curved portion 46 is adhered to and fixed to the outer peripheral surface.

Note that FIGS. 4 to 6 show a state in which one adhesive surface of the double-sided tape 58 is attached to the inner peripheral surfaces of the one end 51 and the other 52 of the hook cover 50, respectively. A state in which the release paper 59 remains on the other adhesive surface is shown. That is, when the hook cover 50 is adhered and fixed to the hook 40 by the double-sided tape 58, the hook cover 50 is fitted in the locking region E of the hook 40, and then the release paper 59 is peeled off and adhered. ..

Therefore, as shown in FIG. 5, the release paper 59 has a predetermined length H (for example, H) outward in the axial direction from the end faces of one end 51 and the other 52 of the hook cover 50 so that the release paper 59 can be gripped by fingers. = 10 mm) is projected. Further, in the plan view shown in FIG. 5, the width W of the adhesive surface of the double-sided tape 58 is, for example, W = 5 mm to 10 mm, and the length D of the adhesive surface of the double-sided tape 58 along the axial direction is For example, it is set to 5 mm to 20 mm.

Further, as shown in FIG. 7, a plurality of slit portions 54 and 56 along the circumferential direction are formed in a predetermined region G axially inside the one end portion 51 and the other end portion 52 of the hook cover 50, respectively. ing. More specifically, this region G includes a region that is tensilely deformed by the first curved portion 44 and the second curved portion 46 and a region that is compressively deformed. Then, for example, six slit portions 54 are formed on the outer peripheral surface in the region on the tensile deformation side, and for example, four slit portions 56 are formed on the outer peripheral surface in the region on the compression deformation side.

The slit portion 54 formed on the outer peripheral surface on the tensile deformation side is cut in a straight line perpendicular to the axial direction in a normal cross-sectional view along the axial direction of the hook cover 50 in a state where it is not fitted to the hook 40. It is formed. The slit portion 56 formed on the outer peripheral surface on the compression deformation side is cut out in an inverted "V" shape in a normal cross-sectional view along the axial direction of the hook cover 50 in a state where it is not fitted to the hook 40. It is formed by. As an example, the slit portions 54 are formed at intervals of 7 mm to 10 mm in the axial direction, and the slit portions 56 are 10 mm to 12 mm in the axial direction when the maximum cut width K on the outer peripheral surface is 2 mm to 3 mm. It is formed at intervals of.

Further, the length J outside the slit portions 54 and 56 (region G) of the hook cover 50 in the axial direction is, for example, J = 8 mm to 12 mm. Considering that the double-sided tape 58 is attached to the inner peripheral surfaces of the hook cover 50 at one end 51 and the other end 52, the slit portions 54 and 56 should not reach the inner peripheral surface of the hook cover 50. It is preferable, but it may be reached. Further, except for FIG. 7, the slit portions 54 and 56 are not shown.

Further, the bus 12 in the present embodiment is assumed to travel in a special section at a speed of 20 km / h or less. Therefore, even if a load toward the front side is applied to the wheelchair 60, such as when the bus 12 suddenly brakes, the lashing belt 30 for fixing the wheelchair 60 to the bus 12 is provided for each wheelchair 60. One is enough.

Next, the operation of the vehicle wheelchair fixing device 10 according to the present embodiment having the above configuration will be described.

As shown in FIGS. 2 and 8, the hook cover 50 is first attached to the hook 40. That is, the hook cover 50 is fitted in the locking region E of the hook 40. Specifically, the hook cover 50 is arranged so as to include a part of the first curved portion 44 on the straight portion 45 side, the straight portion 45, and the second curved portion 46.

Then, the release paper 59 of the double-sided tape 58 attached to the inner peripheral surfaces of the one end 51 and the other end 52 of the hook cover 50 is peeled off, and the inner circumference of the hook cover 50 at one end 51 and the other end 52 is peeled off. The surfaces are adhered to the outer peripheral surface of the first curved portion 44 and the outer peripheral surface of the second curved portion 46, respectively, to fix the hook cover 50 to the hook 40.

As a result, it is possible to effectively suppress or prevent the hook cover 50 from being displaced from the locking region E in the hook 40. More specifically, the position where one end 51 of the hook cover 50 exceeds the boundary 43 between the base 42 and the first curved portion 44, or the other end 52 of the hook cover 50 exceeds the tip 48. It is possible to effectively suppress or prevent the deviation.

Further, when the hook cover 50 is fixed to the hook 40, the region G inside the one end portion 51 and the other end portion 52 of the hook cover 50 in the axial direction is along the first curved portion 44 and the second curved portion 46, respectively. Be curved. However, since a plurality of slit portions 54 and 56 are formed in the region G (see FIG. 7), the inner peripheral surfaces of the one end portion 51 and the other end portion 52 of the hook cover 50 are the outer periphery of the first curved portion 44. It can be brought into close contact with the surface and the outer peripheral surface of the second curved portion 46 (so that they do not rise from the outer peripheral surface).

In particular, the slit portion 54 formed on the tensile deformation side is formed linearly in a normal cross-sectional view along the axial direction of the hook cover 50 in a state where it is not fitted to the hook 40, so that the region on the tensile deformation side is formed. G can be effectively elastically deformed so that the space between the slit portions 54 is widened along the first curved portion 44 and the second curved portion 46. Therefore, the inner peripheral surfaces of the one end 51 and the other 52 of the hook cover 50 on the tensile deformation side can be further brought into close contact with the outer peripheral surface of the first curved portion 44 and the outer peripheral surface of the second curved portion 46.

The slit portion 56 formed on the compression deformation side is formed in an inverted "V" shape in a normal cross-sectional view along the axial direction of the hook cover 50 in a state where it is not fitted to the hook 40. The region G on the deformation side can be effectively elastically deformed so that the space between the slit portions 56 is narrowed along the first curved portion 44 and the second curved portion 46. Therefore, the inner peripheral surfaces of the one end 51 and the other 52 of the hook cover 50 on the compression deformation side can be further brought into close contact with the outer peripheral surface of the first curved portion 44 and the outer peripheral surface of the second curved portion 46.

After fixing the hook cover 50 in the locking region E of the hook 40 in this way, the hook 40 is hooked on the frame 62 of the wheelchair 60 (see FIG. 1). That is, the hook cover 50 arranged in the locking region E of the hook 40 is hooked (locked) on the frame 62. Then, as shown in FIG. 9, a part of the hook cover 50 is elastically deformed and bites into the frame 62. Therefore, the position of the hook 40 with respect to the frame 62 can be stabilized even in an emergency such as when the bus 12 suddenly brakes.

Further, since the hook 40 is locked to the frame 62 via a urethane hook cover 50 having an energy absorbing function, the hook 40 is not in direct contact with the frame 62 (the hook 40 and the frame 62 are not in direct contact with each other). A hook cover 50 is interposed between them, leaving a thickness M). Therefore, the shaking (vibration) applied to the bus 12 can be suppressed by the hook cover 50 from being directly transmitted to the wheelchair 60 via the lashing belt 30.

Further, when removing the lashing belt 30, for example, even when the hook 40 is to be removed from the frame 62 without loosening the lashing belt 30, the hook 40 is not in direct contact with the frame 62. , The hook cover 50 can be slid with respect to the frame 62 while being elastically deformed. Specifically, for example, the hook cover 50 can be slid while being elastically deformed with a force of 0.01 kN. Therefore, the hook 40 can be easily removed from the frame 62 (workability when removing the lashing belt 30 from the frame 62 can be improved).

Moreover, in the hook cover 50 according to the present embodiment, the second curved portion 46 and the tip portion 48 in which the end surface 52A on the compression deformation side of the other end portion 52 is the end portion of the curvature of the second curved portion 46 of the hook 40. Since it extends only to the position where it reaches the boundary portion 47 with the hook 40, the hook 40 can be removed from the frame 62 more easily (workability when removing the lashing belt 30 from the frame 62 is further improved. be able to).

Specifically, when the end face 52A on the compression deformation side of the other end 52 of the hook cover 50 extends to a position reaching, for example, the end face 48A of the tip 48 of the hook 40, the frame 62 to the hook 40 When the tip 48 is removed, the contact area (sliding resistance) between the other end 52 of the hook cover 50 covering the tip 48 and the frame 62 is elastically deformed by the other end 52 of the hook cover 50. It becomes a little difficult to remove because it becomes larger due to the presence.

On the other hand, in the hook cover 50 according to the present embodiment, as described above, the end surface 52A on the compression deformation side of the other end portion 52 extends only to the position where the end surface 52A on the compression deformation side reaches the boundary portion 47 of the hook 40, and the hook. The tip 48 of the 40 is exposed without being covered by the hook cover 50. Therefore, when the tip 48 of the hook 40 is removed from the frame 62, the contact area between the tip 48 and the frame 62 becomes a small point between the arcuate surfaces that intersect each other and come into contact with each other. Easy to remove.

Further, when the passenger P of the wheelchair 60 is not on board, the lashing belt 30 is placed in a predetermined place. Therefore, the lashing belt 30 and the hook 40 may move due to the shaking (vibration) applied to the bus 12. Here, the hook 40 is provided with a urethane hook cover 50 as described above.

Therefore, even if the hook 40 moves and the hook cover 50 hits other surrounding parts (for example, the wall surface such as the wheelchair 60, the floor surface 14, or the side wall of the passenger compartment S), the other parts may be damaged or abnormal noise may be generated. There is no. Further, since the hook cover 50 is made of urethane, the weight of the hook cover 50 can be reduced as compared with the case where the hook cover 50 is not made of urethane. Further, when the hook cover 50 is deteriorated, it is sufficient to replace it.

On the other hand, the locked portion 32 of the lashing belt 30 is detachably locked to the anchor 20 as follows. That is, as shown in FIG. 10A, in a state where the rod portion 36 is pressed downward against the urging force of the coil spring, the pressing portion 38 is pressed against the main body portion 22 of the anchor 20 and the front overhanging portion. It is inserted into the gap (insertion port) between the 24 and the rear overhanging portion 26 from the inside or the outside in the vehicle width direction. Then, the downward pressure of the rod portion 36 is released at the central portion of the anchor 20.

Then, as shown in FIG. 10B, the engaging portions 35 are engaged (entered) on the left and right sides of the front overhanging portion 24 and the rear overhanging portion 26, and the front overhanging portion 24 and the rear side are engaged with each other. The upper end of the overhanging portion 26 is sandwiched between the upper surface of the pressing portion 38 and the lower surface of the main body portion 34 by the urging force of the coil spring. As a result, the locked portion 32 of the lashing belt 30 can be locked with respect to the anchor 20 in a state in which movement of the anchor 20 is restricted up and down, front and back, and left and right.

When removing the locked portion 32 of the lashing belt 30 from the anchor 20, the rod portion 36 is pressed downward against the urging force of the coil spring. Then, in that state, the pressing portion 38 may be pulled out from the gap between the main body portion 22 of the anchor 20, the front overhanging portion 24, and the rear overhanging portion 26.

The vehicle wheelchair fixing device 10 according to the present embodiment has been described above with reference to the drawings, but the vehicle wheelchair fixing device 10 according to the present embodiment is not limited to the one shown in the drawing, and is a gist of the present invention. The design can be changed as appropriate within the range that does not deviate from. For example, the hook cover 50 is not limited to urethane, and the adhesive means is not limited to the double-sided tape 58.

Further, the double-sided tape 58 as the adhesive means may be provided only on the one end 51 or the other end 52 instead of the one end 51 and the other end 52 of the hook cover 50. Further, the dimensions of each part of the hook cover 50 and the quantities of the slit parts 54 and 56 are examples, and are not limited to the above. The dimensions of each part of the hook cover 50 and the quantities of the slit parts 54 and 56 are appropriately redesigned according to the shape and outer diameter of the hook 40 and the like.
